INVALID LIFTER AND CONVEYER.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed January 1c, 1918. Serial No. 212,080.

To all whom it may concern:

Be it known that I, ADALINE M. TANNER, a citizen of the United States, residing at Devils Lake, in the county of Ramsey and State of North Dakota, have invented certain new and useful Improvements in Invalid Lifters and Conveyers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in invalid lifters and conveyers, and particularly to that type used in hospitals, sanatoriums and the like, whereby patients may be readily and quickly lifted to be transported from one place to another and their positions in bed changed.

The object of this invention is to provide a device capable of being moved to and about a. bed so that the patient may be readily lifted vertically from the bed to permit his position to be changed or taken to another place as desired.

A further object of this invention is to provide a pad or mattress upon which the patient lies and to provide a means capable of being removably secured to this pad or mattress whereby the patient may be raised or lowered as desired.

Another object of this invention is to provide a device of this character, which will be simple, practical and comparatively inexpensive in construction, and one that can be manufactured and "sold at a low cost.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts hereinafter more fully described and set forth in the claim hereto appended.

In the drawings:

Figure 1 is a side elevation of the improved invalid lifter and conveyer constructed in accordance with this invention.

Fig. 2 is a top plan View of the same.

Fig. 3 is an end elevation.

Fig. 4 is a fragmentary sectional view.

Fig. 5 is a plan View of the patient supporting mattress or pad.

Fig. 6 is a fragmentary sectional view of the frame holding device.

Fig. 7 is a fragmentary detail sectional view illustrating the manner in which the pad is held against longitudinal or lateral movement with relation to the supporting frame or carrier.

Like numerals of reference designate cor responding parts in all the figures of the drawings.

Referring to the drawings, the numeral fi indicates a supporting structure in its entirety and it includes a plurality of vertical standards 6. The standards 6 are arranged in spaced pairs and have their upper ends connected by, the end rails 7 and side rails 8.

A pair of relatively spaced shafts 9 are journaled in the end rails 7 centrally thereof. The ends of the shafts 9 are reduced and are j ournaled in the end rails 7 and extend beyond the other sides thereof and have secured to their terminals meshing gears 10. A sprocket wheel 11 is secured to one of the gears 10. and has trained thereover a sprocket chain 12.

A brace rod 13 is connected to one pair of the standards 6 below one end rail 7 and has secured centrally thereto a sprocket wheel 14. The sprocket wheel 14 is journa'led to the brace rod 13 in direct alinement with the sprocket wheel 11 of one of the gears 10 so as to receive the chain 12. A crank handle 15 is secured to the sprocket wheel 14 so that the latter may be rotated for rotating the shafts 9, the purpose of which will be hereinafter more fully described. v

A pair of rollers 16 have their ends journaled in the end rails 7 of the supporting structure. The rollers 16 are engaged by flexible straps 17 secured at 18 to the frame 20 so that upon the rotation of the shafts 9, the frame 20 will be elevated. The rollers 16 are positioned close to the side rails 8. The flexible straps 17 are arranged in spaced relation and have their inner ends permanently secured to the shafts 9.

The free ends of the straps 17 are secured as at 18 to side rails 19 of a lifting frame 20. The lifting frame 20 comprises the side rails 19 and end rails 21 so as to provide a substantially rectangular structure, the interior diameter of which is greater than the diameter of the mattress or pad 22.

The mattress or pad 22 comprises a rectangular frame covered by suitable fabric 23 and the side and end rails of this pad are adapted to have secured thereto a plurality of relatively spaced attaching flaps 24, each of which is provided in its outer terminal with an aperture 25 which permits these flaps to be attached to suitable buttons or other fastening means carried by the exterior of the side and ends rails of the lifting frame 20. The pad or mattress 23 is adapted to be positioned upon the mattress of a bed designated A in the drawings and the patient is adapted to lie upon this pad or mattress 28. The supporting structure 5 is moved to and about the bed so as to position its lifting frame directly over the mattress or pad 23. By rotating the crank 15 in one direction, the lifting frame will be lowered to and about the supporting pad or mattress 23. The attaching 'flaps 2a are then fixed to the side and end rails of the lifting frame and by rotation of the crank in the opposite direction the frame will be lifted, raising the supporting pad upon which the patient is positioned.

The standards 6 each have journaled in the lower ends thereof suitable ro'llers 26 Which permit them to be readily moved to various places. Each standard 6 is also provided intermediate its ends with a suitable socket 27 which is adapted to receive a ball 28 formed on the end of an arm 29. The free end of the arm 29 is pivotally secured to each end of each side rail 19 of the lifting frame 20, as at 30. Thus, it can be seen that, when the mattressor pad is attached to the lifting frame and the patient has been raised and removed from the bed, it is only necessary to lower the lifting frame until the arms can be swung into a horizontal plane and move their balls or heads 28into the sockets 27 in order to hold the liftin frame and mattrws against lateral or longitudinal movement with relation to the supporting structure.

Inuse, the mattress or pad 23 is first laid upon the bed and the patient placed thereon. lhe supporting structure is then moved about and over the bed until the lifting frame is directly over the pad 23 and the crank is turned in one direction rotatingthe shaft which permits the lifting frame to be lowered through the medium of the flexible straps'17. By virtue of the diameter of the frame being greater thanthe area of the pad or mattress, it will readily fit thereover. The attaching strap 24 are then attached to pins or studs 25 formed on the lifting frame, thus removably connecting the pad or mattress thereto, and by reverse rotation of the crank the lifting frame will be raised ver tically until the-mattress or pad is clear of the head and foot board of the bed to permit the supporting structure to be moved away from the bed. Theelifting frame is then lowered and the arms 29 swung into a hori- Zontal plane, moving the heads 28 into the sockets 27 thus the frame and pad are held against any relative movement with relation to the supporting structure.

Having thus described my invention what I claim is:

An invalid lifter including a supporting frame having vertical standards and horizontal connecting members, a pair of operating shafts extending longitudinally of the frame, means connecting the shafts for oper ating the same in unison, longitudinally disposed rollers rotatably carried by the frame, a lifting frame arranged within the supporting frame, a lifting pad detachably connected to the lifting frame, spaced lifting straps secured to the lifting frame and extending over said rollers and having their inner ends secured to said shafts, sockets carried by the standards of said supporting frame, and horizontally pivoted arms carried by said lifting frame for engaging said sockets whereby any longitudinal movement of the lifting pad is prevented.

' In testimony whereof I affix my signature in presence of two witnesses.
